Hi Adam,

colored light has nothing to do with colored material !


scolor[th_]:=Which[th<Pi/3,GrayLevel[0.8],
	           Pi/3<=th && th<2Pi/3,GrayLevel[0.4],
                   True,GrayLevel[0.8]
             ]

SphericalPlot3D[{1,scolor[th]},{th,0,Pi},{phi,0,2Pi},Lighting->False]

will do what you want without any light.

Hope that helps
  Jens
